Start with the material you actually cut
The first question is simple: what will go on the bed most often? Plywood, MDF, acrylic, HDPE, foam, aluminium sheet and composite board all behave differently. A router that handles kitchen cabinet parts may not suit sign panels with fine lettering or aluminium trims.
Material thickness matters too. If you only ever cut 16 mm board, you do not need the same Z travel or spindle setup as a shop doing 30 mm parts and nested sheet work. Ask about chip load, cutter size and hold-down method before you look at table size. That saves money and stops false expectations.
- List your main materials by percentage, not just by name.
- Note the thickest sheet or profile you expect to process.
- Say whether the work is through-cutting, engraving, pocketing or drilling.
- Ask what tooling is best for each material, not only what the machine can move.
Match the router to your weekly workload
A machine for ten sheets a week is a very different decision from one that must run every day on back-to-back orders. The amount of cutting time, tool changes and operator handling should guide the spec. A small sign shop may need easy setup and quick learning. A furniture maker may need repeatability and nesting for full board use.
Think about peak weeks, not only average weeks. If month-end means overtime and long runs, ask about spindle duty cycle, vacuum stability and controller memory. A machine that is fine for occasional use can become a problem when the workshop is under pressure.
- Estimate sheets or parts per day in a busy week.
- Say if the router must work one shift or more than one.
- Ask how long tool changes and job changeovers take.
- Check whether the control system is easy for new operators to learn.
Measure the workshop, then add working space
Many first-time buyers measure only the machine footprint. That is not enough. You need space for loading sheets, walking around the table, opening the cabinet, moving a vacuum line and keeping finished parts clear of dust. In a Germiston workshop with limited floor area, 3 metres by 6 metres on paper can become very tight once the router is delivered and cable runs are added.
Also check access. Can the machine get through the door, around the corner and into position without major building work? If you are on an upper floor or a site with narrow gates, machine size is only part of the story.
- Measure the machine space and the loading space separately.
- Allow room for dust extraction, electrical isolation and tool storage.
- Check door widths, gate access and floor level changes.
- Plan for part stacking and sheet movement after cutting.
Power, dust and workshop conditions change the outcome
South African workshops have to deal with load-shedding, voltage dips, coastal humidity in some areas and dust everywhere. A router needs stable power, proper earthing and sensible protection on the electrical side. If the supply is weak, ask whether a power conditioner, backup plan or controlled shutdown process is needed.
Dust extraction is just as important. Poor dust removal shortens tool life, affects cut quality and makes daily cleaning a chore. In humid coastal towns, moisture can also affect boards, tooling and cabinets. The machine should fit the workshop, not only the product catalogue.
- Ask what incoming power the machine needs and what protection is recommended.
- Check whether the workshop can handle the vacuum pump and extraction load at the same time.
- Find out how the machine behaves during a power interruption.
- Ask about dust hooding, vacuum zones and cleaning access.
Support matters more than most first buyers expect
When a new team starts on CNC, support is not an extra. It is part of the purchase. You need help with installation, commissioning, operator training, tooling setup, controller backups and practical troubleshooting. A machine that is technically sound but poorly set up can waste days of production.
Ask who will show the team how to use it, who can help with spindle service and who handles preventive maintenance. If your site is outside Gauteng, check response times for installation and call-out support. In South Africa, distance and road travel can affect downtime far more than many buyers expect.
- Confirm installation and commissioning dates before delivery.
- Ask what training is included for operators and supervisors.
- Check if backups, service logs and tooling notes are part of the handover.
- Find out how parts, tooling and maintenance support are handled after sale.
A practical first-buy example from Germiston
A small Germiston joinery shop wanted to move from hand cutting to nested parts for cabinets and carcasses. The team had limited floor space, one main operator and frequent power interruptions in the area. Instead of choosing the biggest table available, they looked at board size, daily throughput and how quickly jobs had to be turned around.
The questions led them to a machine that fit the room, supported their sheet sizes and allowed cleaner dust removal. They also planned for controller backups and a simple shutdown routine during load-shedding. That meant fewer scrap pieces, steadier output and less pressure on the operator during busy weeks.
For first-time buyers, that is the point. The right router is not the one with the longest list of features. It is the one that suits your material, your pace and your workshop reality.
Questions worth asking before you sign off
Before you commit, write your questions down and keep them practical. The answers should be specific, not vague. If the supplier can explain setup, service and operating limits clearly, you are already in a better position to make a sound decision.
- What material will this machine handle best?
- How much daily work is it sized for?
- Will it fit our workshop and loading area?
- What power and dust extraction does it need?
- Who supports installation, training and after-sales service?
Those five questions will tell you far more than a glossy brochure. They also help you compare options on real workshop terms instead of guesswork.
